At the funeral, a singer reworked Dylan’s favorite song from Shrek, “Hallelujah,” to pay tribute to Dylan and the other victims.

"Hallelujah - a supposedly religious pop song with Sadism and Masochism overtones, written by a man who strongly identifies with 17th century False Messiah Sabbatai Zvi."
Shrek links to butterflies.

Butterflies in Shrek.

"Because I am a beautiful butterfly" - spoken by a 6 year old whose favourite movies are said to have included Shrek and whose favourite colour is "said" to have been purple, ditto for fellow victims, Oliver Engel and Josephine Gay.

Grace Audrey McDonnell's Mum Lynn:

"She just had a birthday in November when she turned 7 and ... she said, 'I want a purple cake...'"

Sandy Hook substitute teacher, Lauren Rousseau:

"It helped that she still lived in her purple room in the sprawling, warmly decorated Victorian house she was born in ..."

Well mind control, somewhere over the rainbow, funny that song always gave me the creeps even from when I was a very young child. Wouldn't you guess Ariana Grande sings it at end of tribute to Manchester arena attack and releases it as a charity single. https://www.google.co.uk/amp/www.mirror.co.uk/3am/celebrity-news/ariana-grande-releases-somewhere-over-10580920.amp
